Incorrect parsing POP3 packet (#4 in attachment) -- response to CAPA command.



RFC 2449:

An -ERR response indicates the capability command is not implemented and the
client will have to probe for capabilities as before. 
An +OK response is followed by a list of capabilities, one per line. Each
capability name MAY be followed by a single space and a space-separated list of
parameters. Each capability line is limited to 512 octets (including the CRLF).
The capability list is terminated by a line containing a termination octet
(".") and a CRLF pair. 

Possible Responses: +OK -ERR 
Examples:
C: CAPA 
S: +OK Capability list follows 
S: TOP 
S: USER 
S: SASL CRAM-MD5 KERBEROS_V4 
S: RESP-CODES 
S: LOGIN-DELAY 900 
S: PIPELINING 
S: EXPIRE 60 
S: UIDL 
S: IMPLEMENTATION Shlemazle-Plotz-v302
